9112a5be58 vkd3d-shader/ir: Move DCL_TEMPS removal to the generic instruction lowering pass. 2024-04-15 21:33:34 +02:00

8a17a5a08b vkd3d-shader/ir: Introduce vsir_program_lower_instructions(). 
It is meant as generic pass to host all program changes to single
instructions that do not require keeping a global state, intstead
of having to loop through the whole program many times.

b4cfc24f67 vkd3d-shader/ir: Refactor declaration emission outside of the CFG structure. 
This is in preparation of handling more than one function (as
it happens for Hull Shaders), which will require having a single
row of declarations, but handling more than one CFG.

cfcd57209b vkd3d-shader/ir: Convert SSAs to temps only if the block of origin does not dominate all uses. 2024-04-09 12:27:19 -05:00

7bfc7410f2 vkd3d-shader/ir: Materialise phis to temps in the incoming blocks. 
RADV converts temps to phi instructions, so converting phis to MOVC in
VSIR just translates back to phis feeding into a MOVC. This commit
eliminates the MOVC.

9aff65c6d2 vkd3d-shader/ir: Open a loop when visiting the loop header. 
Not when making the loop header available, which is too early and
might lead to open too many loops at once.

d10031911d vkd3d-shader/ir: Move vsir_program_normalise() to the end of the file. 
vsir_program_normalise() has function calls to basically everything in
ir.c, so it's useful to have it in an easily reachable place to
quickly jump to wherever you need using your favorite code editor's
features.

e5f486edd3 vkd3d-shader/ir: Use type "unused" for labels. 
The label itself is certainly an unsigned integer, but the register
has no meaningful data type. It cannot be evaluated to anything.
The goal of this is to reduce cluttering in the internal ASM dumps.

8c15377ffc vkd3d-shader/ir: Emit multilevel jumps in the structured program. 
The new structurizer therefore reaches feature parity with the
older simple one, except for a couple of points:

 * the old structurizer accepts any CFG, without requiring reducibility;
   however, the DXIL specification requires the CFG to be reducible
   anyway, so we're not really losing anything;

 * the new structurizer additionally requires that no block has two
   incoming back arrows; AFAIK this is condition that can happen,
   but in practice it seems to be rare; also, it's not hard to add
   support for it, as soon as it is decided it is useful.

On the other hand, the new structurizer makes use of the merging
information that are reconstructed from the CFG, which is important
for downstream optimization and fundamental for correctly emitting
tangled instructions.

Taking these considerations into account, the old structurizer is
considered superseded and is therefore removed.

c2aa01de6e vkd3d-shader/ir: Emit the reconstructed structured program. 
Multilevel jumps are not supported yet, and trigger a fallback to the
simple structurizer.
